Overhanging die shear

The precision of our Sigma range has the accuracy for the most challenging applications. Overhanging die shear tests are the perfect solution for testing stacked devices. But this requires precise tool landing and alignment. In addition, the overhanging die can cause inconsistent shear height because the tool landing force and shear down thrust will change the shear height.


There is no way to eliminate the deflection, but it is possible to minimize it. A programmable landing force of 2 grams reduces the deflection when landing, improving the step-back accuracy.
